Short Wave Infrared (SWIR) band is an interesting waveband for a lot of industrial applications like process control, spectrometry, telecommunications and space as well as for military applications like eye-safe laser imaging. The detectors available in this waveband are based on silicon with a 1.1 μm cut-off wavelength and on InGaAs with 1.6_2 μm cut-off but also on HgCdTe material (MCT), which is a good candidate to answer systems needs with relatively high cut-off wavelength, typically up to 2 or 2.5 μm. All these detectors are T.E. cooled or uncooled allowing cost-effective design approaches. To answer commercial application needs, a lot of trade-offs can be made at level of the SWIR detectors in order to optimize the performances and the associated packaging with the goal to offer cost-effective detectors. As far as military applications are concerned, specific developments are needed in order to fulfill the requirements of future systems. The different needs and detector options are reviewed and discussed in this paper. |
